CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. 119 to Korean Patent Application No. 10-2019-0036087 filed on Mar. 28, 2019 in the Korean Intellectual Property Office, the disclosure of which is herein incorporated by reference in its entirety.

BACKGROUND 1. Field

Various embodiments relate to a method for installing a subscriber profile and an electronic device therefor.

2. Description of Related Art

A universal integrated circuit card (UICC) is a smart card which is inserted into a mobile communication terminal for use. A UICC may store personal information about a mobile communication subscriber and enables the use of secure mobile communication via subscriber authentication and traffic security key in accessing to a mobile communication network.

A UICC is manufactured as a dedicated card for a particular mobile communication operator by request of the operator at the time of manufacture of the card and may be released with authentication information of the operator for network access, for example, a universal subscriber identity module (USIM) application and an international mobile subscriber identity (IMSI), loaded in advance. The mobile communication operator receives the manufactured UICC card and provides the UICC card for a subscriber. If necessary, it is possible to manage, for example, install, modify, or delete, an application in the UICC card using an over-the-air (OTA) technology or the like. The subscriber may insert the UICC card into a mobile communication terminal to use a network and an application service of the mobile communication operator. When the existing terminal is replaced with a new terminal, the subscriber can insert the UICC card into the new terminal, thereby using the same authentication information, mobile phone number, and personal contacts as stored in the UICC card in the new terminal.

A UICC can be replaced by embedding a security module performing a function similar to that of a UICC in a mobile communication terminal at the time of manufacture of the terminal. Therefore, an embedded universal integrated circuit card (eUICC) structure, which is an undetachable UICC, has been proposed.

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

SUMMARY

Network lock may be restricting the use of an electronic device to block network-related functions when an invalid subscriber identity module (SIM) card is inserted into the electronic device with a valid SIM card inserted. For example, when restrictions are imposed so that an electronic device released in a country can recognize only a SIM card of a network operator of the country or can recognize only a SIM card of a specified network operator in the country, network lock may occur to the electronic device. When the invalid SIM card is a plastic SIM card, network lock may be released by physically removing the invalid plastic card from the electronic device having the network lock. When the invalid SIM card is an embedded subscriber identity module (eSIM) card, it is impossible to remove the invalid eSIM card from the electronic device having network lock, and thus network-related functions may be blocked.

Various embodiments provide a method for installing a subscriber profile and an electronic device thereof.

According to various embodiments, an operating method of an electronic device may include: obtaining network operator-related information; identifying whether download of an embedded subscriber identity module (eSIM) profile is allowed based on the network operator-related information; and downloading the eSIM profile when download of the eSIM profile is allowed.

According to various embodiments, an electronic device may include: a display; a communication unit; and a processor configured to be operatively connected to the display and the communication unit. The processor may perform control to: obtain network operator-related information; identify whether download of an embedded subscriber identity module (eSIM) profile is allowed based on the network operator-related information; and download the eSIM profile when download of the eSIM profile is allowed.

A method and an electronic device thereof according to various embodiments may identify in advance whether network lock occurs before downloading an embedded subscriber identity module (eSIM) profile, thereby preventing network lock which occurs by downloading an eSIM profile.

Further, a method and an electronic device thereof according to various embodiments may obtain information about a network operator which causes network lock, thus configuring a list of network operators which allow download of an eSIM profile.

For example, the sensor module 176 (e.g., a fingerprint sensor, an iris sensor, or an illuminance sensor) may be implemented as embedded in the display device 160 (e.g., a display).

The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to one embodiment, as at least part of the data processing or computation, the processor 120 may load a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134. According to an embodiment, the processor 120 may include a main processor 121 (e.g., a central processing unit (CPU) or an application processor (AP)), and an auxiliary processor 123 (e.g., a graphics processing unit (GPU), an image signal processor (ISP), a sensor hub processor, or a communication processor (CP)) that is operable independently from, or in conjunction with, the main processor 121. Additionally or alternatively, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be specific to a specified function. The auxiliary processor 123 may be implemented as separate from, or as part of the main processor 121.

The auxiliary processor 123 may control at least some of functions or states related to at least one component (e.g., the display device 160, the sensor module 176, or the communication module 190) among the components of the electronic device 101, instead of the main processor 121 while the main processor 121 is in an inactive (e.g., sleep) state, or together with the main processor 121 while the main processor 121 is in an active state (e.g., executing an application). According to an embodiment, the auxiliary processor 123 (e.g., an image signal processor or a communication processor) may be implemented as part of another component (e.g., the camera module 180 or the communication module 190) functionally related to the auxiliary processor 123.

The memory 130 may store various data used by at least one component (e.g., the processor 120 or the sensor module 176) of the electronic device 101. The various data may include, for example, software (e.g., the program 140) and input data or output data for a command related thereto. The memory 130 may include the volatile memory 132 or the non-volatile memory 134.

The program 140 may be stored in the memory 130 as software, and may include, for example, an operating system (OS) 142, middleware 144, or an application 146.

The input device 150 may receive a command or data to be used by other component (e.g., the processor 120) of the electronic device 101, from the outside (e.g., a user) of the electronic device 101. The input device 150 may include, for example, a microphone, a mouse, a keyboard, or a digital pen (e.g., a stylus pen).

The sound output device 155 may output sound signals to the outside of the electronic device 101. The sound output device 155 may include, for example, a speaker or a receiver. The speaker may be used for general purposes, such as playing multimedia or playing record, and the receiver may be used for an incoming calls. According to an embodiment, the receiver may be implemented as separate from, or as part of the speaker.

The display device 160 may visually provide information to the outside (e.g., a user) of the electronic device 101. The display device 160 may include, for example, a display, a hologram device, or a projector and control circuitry to control a corresponding one of the display, hologram device, and projector. According to an embodiment, the display device 160 may include touch circuitry adapted to detect a touch, or sensor circuitry (e.g., a pressure sensor) adapted to measure the intensity of force incurred by the touch.

The audio module 170 may convert a sound into an electrical signal and vice versa. According to an embodiment, the audio module 170 may obtain the sound via the input device 150, or output the sound via the sound output device 155 or a headphone of an external electronic device (e.g., an electronic device 102) directly (e.g., wiredly) or wirelessly coupled with the electronic device 101.

The sensor module 176 may detect an operational state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) external to the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state. According to an embodiment, the sensor module 176 may include, for example, a gesture sensor, a gyro sensor, an atmospheric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The interface 177 may support one or more specified protocols to be used for the electronic device 101 to be coupled with the external electronic device (e.g., the electronic device 102) directly (e.g., wiredly) or wirelessly. According to an embodiment, the interface 177 may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface.

A connecting terminal 178 may include a connector via which the electronic device 101 may be physically connected with the external electronic device (e.g., the electronic device 102). According to an embodiment, the connecting terminal 178 may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector).

The haptic module 179 may convert an electrical signal into a mechanical stimulus (e.g., a vibration or a movement) or electrical stimulus which may be recognized by a user via his tactile sensation or kinesthetic sensation. According to an embodiment, the haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.

The camera module 180 may capture a still image or moving images. According to an embodiment, the camera module 180 may include one or more lenses, image sensors, image signal processors, or flashes.

The power management module 188 may manage power supplied to the electronic device 101. According to one embodiment, the power management module 188 may be implemented as at least part of, for example, a power management integrated circuit (PMIC).

The battery 189 may supply power to at least one component of the electronic device 101. According to an embodiment, the battery 189 may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell.

The communication module 190 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the SIM 196.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network 198 or the second network 199, may be selected, for example, by the communication module 190 (e.g., the wireless communication module 192) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 and 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 101. The electronic device 101 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.

FIG. 2 illustrates a system including an electronic device that supports an embedded subscriber identity module (eSIM) function according to various embodiments.

An eSIM may be embedded in the electronic device 210, and the electronic device 210 may access an external server to download a profile of the eSIM in a software package. To remove the eSIM, software corresponding to the eSIM may be deleted from the electronic device 210. The eSIM is a logical concept and may exist physically inside an embedded universal integrated circuit card (eUICC) 212.

Referring to FIG. 2, the electronic device 210 (e.g., the electronic device 102 of FIG. 1) may include a local profile assistant in the device (LPAd) 211 and the eUICC 212. The LPAd 211 may be a software module installed in the electronic device 210. The LPAd 211 may assist in installing the profile of the eSIM, downloaded from the external server (e.g., a subscription manager for data preparation (SM-DP) 230), in the eUICC. For example, the LPAd 211 may retrieve the external server, may download the profile of the eSIM, and may forward the profile to the eUICC. The LPAd 211 may deactivate or remove a previously installed eSIM profile. The LPAd 211 may include a local discovery service when a local profile assistant (LPA) is in the device (LDSd), which manages a connection between a subscription manager discovery server (SM-DS) 240 and the LPAd 211, a local profile download when the LPA is in the device (LPDd), which manages download of an eSIM profile, and a local user interface when the LPA is in the device (LUId), which manages a user interface (UI) of the LPAd 211. The eUICC 212 may be a physical card in which an eSIM profile is installed.

An operator 220 may be an operator that provides a wireless network service for the electronic device 210. For example, when the electronic device 210 makes a network subscription request to the operator 220 to join the network, the operator 220 may generate an eSIM profile based on personal information about the electronic device 210 and may provide the generated eSIM profile to the SM-DP. The SM-DP 230 may be a server that stores the eSIM profile of the electronic device 210. For example, the electronic device 210 supporting the eSIM function may retrieve the SM-DP to connect to an SM-DP server and may retrieve and download the eSIM profile of the electronic device 210 from the SM-DP. An SM-DS 240 may be a server that retrieves the SM-DP 230 requested by the electronic device 210. The electronic device 210 may connect directly to the SM-DP 230 without passing through the SM-DS 240. A certificate issuer (CI) 250 may issue a certificate for eSIM provisioning. An eUICC manufacturer (EUM) may be an entity that manufactures an eUICC.

A specific process for downloading the eSIM profile of the electronic device 210 is as follows. The electronic device 210 may make a subscription request through an operator 220. The operator 220 may generate an eSIM profile corresponding to the subscription request of the electronic device 210 and may transmit the generated eSIM profile to the SM-DP 230. The electronic device 210 may access the SM-DS 240 through the LPAd 211 and may receive an address of the SM-DP 230. The electronic device 210 may access the address of the SM-DP 230 received through the LPAd 211. The SM-DP 230 may perform a predefined authentication process, may segment the stored eSIM profile of the electronic device 210, and may transmit the segmented eSIM profile to the LPAd 211 of the electronic device 210. The LPAd 211 may transmit eSIM profile data of the received eSIM profile to the eUICC 212 based on a standard protocol. The transmitted eSIM profile data may be installed as one eSIM profile based on an internal mechanism of the eUICC 212. The LPAd 211 may activate the installed eSIM profile, which may be similar to inserting a plastic SIM card.

FIG. 3 illustrates a method for preventing network lock occurring in an electronic device 101 before installing a subscriber profile according to various embodiments. Referring to FIG. 3, the electronic device 101 may include a plastic SIM card 310 and an eUICC 320 with an eSIM profile not downloaded. The electronic device 101 may download an eSIM profile through a network of the plastic SIM card 310. After downloading the eSIM profile, the electronic device 101 may activate the eSIM profile in the eUICC 320 and may determine whether network lock occurs through a lock validity check process. For example, the network lock may be for putting a restriction so that the electronic device 101 may use a network only with a SIM card having a specific operator's mobile country code (MCC) and/or mobile network code (MNC). With the network lock set, when a SIM card having a different MCC and/or MNC that is not allowed is inserted, a network-related function of the electronic device 101 may be blocked. An MCC is a three-digit country identification code stored in a SIM profile, and may be used to specify a country since each country has one MCC. An MNC is a network operator identification code, and one operator may have one or more MNCs in a single country. For example, a combination of an MNC and an MCC may specify an operator. Since a mobile virtual network operator (MVNO) may rent and use a different operator's circuit network, it may be impossible to distinguish between operators through an MCC and an MNC, and thus a group identifier (GID) may be further used for reference. An integrated circuit card identifier (ICCID) is a 19-digit serial code stored in a SIM profile and may have a unique ICCID value for the SIM profile.

After the electronic device 101 activates the downloaded eSIM profile, when network lock occurs in the electronic device 101, the network-related function may be blocked, and the electronic device 101 may be in a state in which a general phone call or data communication is not supported.

According to various embodiments, to prevent network lock from occurring in the electronic device 101, the electronic device 101 may check whether network lock has occurred before downloading the eSIM profile. According to one embodiment, the electronic device 101 may request network operator-related information from an external server (e.g., the server 108 of FIG. 1 or the SM-DP 230 of FIG. 2) before downloading the eSIM profile. The electronic device 101 may extract identification information, such as an MCC, an MNC, GID1, or GID2, based on the received network operator-related information. The electronic device 101 may check whether download of the eSIM profile is allowed based on the extracted identification information, thereby preventing network lock in advance.

FIG. 4 illustrates a block diagram of an electronic device 101 for installing a subscriber profile according to various embodiments. Referring to FIG. 4, the electronic device 101 may include a processor 410 (e.g., the processor 120 of FIG. 1), an eUICC 420 (e.g., the SIM 196 of FIG. 1), a memory 430 (e.g., the memory 130 of FIG. 1), a display 440 (e.g., the display device 160 of FIG. 1), and/or a communication unit 450 (e.g., the communication module 190 of FIG. 1).

The processor 410 may control the overall operation of the electronic device 101. For example, the processor 410 may control at least one other component (e.g., a hardware or software component) connected to the processor 410 and may perform various types of data processing or operations. According to one embodiment, as at least part of the data processing or operations, the processor 410 may load a command or data received from another component into the memory 430, may process a command or data stored in the memory 430, and may store the resulting data in the memory 430. According to one embodiment, the processor 410 may perform control to obtain network operator-related information from a first server 460 (e.g., the SM-DP 230 of FIG. 2) or a second server 470 (e.g., the server 108 of FIG. 1)) through a network (e.g., the second network 199 of FIG. 1) and to check whether the electronic device 101 is allowed to download an eSIM profile based on the network operator-related information. When downloading the eSIM profile is allowed, the processor 410 may perform control to download the eSIM profile. When downloading the eSIM profile is not allowed, the processor 410 may perform control to stop downloading the eSIM profile or to display a warning message on the display 440.

The processor 410 may include an eSIM controller 411 and/or a lock setting unit 412. These components of the processor 410 may be configured in hardware, in software, or in a combination of hardware and software.

The eSIM controller 411 may collect advance information about the eSIM profile to be downloaded via a connection to the first server 460 (e.g., the SM-DP 230 of FIG. 2) or the second server 470 (e.g., the server 108 of FIG. 1)) through the second network 199. The eSIM controller 411 may include an LPAd, an LDSd, an LPDd, and/or an LUId. The advance information about the eSIM profile may be network operator-related information specifying a network operator of the eSIM profile. According to one embodiment, the advance information about the eSIM profile may be stored in advance in the memory 430 of the electronic device 101. For example, the network operator-related information may be information available to identify the network operator and may include, for example, at least one of eSIM profile metadata, an MCC, an MNC, GID1, GID2, and/or an ICCID. The lock setting unit 412 may check whether network lock occurs in the electronic device 101 based on the collected advance information about the eSIM profile. For example, the lock setting unit 412 may compare the advance information about the eSIM profile with lock setting information about the electronic device 101 stored in the memory 430, thereby determining whether network lock occurs in the electronic device 101.

The eUICC 420 may be a physical card in which the eSIM profile requested by the electronic device 101 is installed. For example, the electronic device 101 may identify and authenticate the electronic device 101 within a communication network (e.g., the first network 198 or the second network 199 of FIG. 1) using subscriber information (e.g., an international mobile subscriber Identity (IMSI)) stored in the eUICC 420.

The memory 430 may store various data used by at least one component (e.g., the processor 410) of the electronic device 101. The data may include, for example, software, the lock setting information about the electronic device 101, and input data or output data about a command associated therewith.

The display 440 may visually and/or audibly provide information to the electronic device 101. For example, the display 440 may include, for example, at least one light emitting diode (LED), a speaker, or a control circuit for controlling a display and may output a sound through an audio output device or an external device (e.g., a speaker or a headphone) connected directly or wirelessly to the electronic device 101.

The communication unit 450 may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and the first server 460 or the second server 470 and performing communication through the established communication channel.
